Aspen Bibliography
The broad genotypic variability in quaking aspen (Populus tremuloides Michx.), that results in equally broad phenotypic variability among clones is important to the ecology and management of this species. This chapter considers principles of aspen genetics and variation. variation in aspen over its range, and local variation among clones. For a more detailed review of the genetics of qualung aspen, especially with wider geographic application and with emphasis on tree breeding, see Einspahr and Winton (1976).

Aspen Bibliography
Anaspen progeny test consisting of 206 families of trembling aspen (Populus tremuloides), bigtooth apsen (P. grandidentata), and their hybrids (P. Xsmithii and P. Xrouleauiana) was planted on five Michigan sites and evaluated after two growing seasons. Growth performance of trembling aspen families when compared with all aspen taxa was above average and increased with the latitude of the plantation site. Backcrosses of trembling aspen males to white poplar-bigtooth aspen (P. Xrouleauiana) females produced the fastest growing families at all Lower Peninsula plantations. Most hybrid aspen (P. Xsmithii) families had growth rates below the planation …
